Application October 26, 1940, Serial No. 363,058 (01. 210-2) 1 Claim.

This inventionfappertains to new and useful improvements in sewage disposal plants and more particularly to those plants in which the sewage to b'etreated is discharged to a settling chamber allowing'the solids to settle through an openbottom into a chamber below, usually termed a sludge chamber where the solids are I allowed to digest for a periodof fromone to six months, as required. After the solids have digested for a sufficient period of time they, are

drawn'ofi for disposal, In the present settling plants the solids, when drawn off; are mixed with raw; solids recently settled. The raw sewage causes considerable odor to emanate from the withdrawn mass.

The principal object of; the present invention is to provide a settling apparatus adapted to keep incoming sewage away 'from sludge which has been or is being digested.

i I Another important object of the invention is to provide an apparatus whereby thoroughly digested sludge can be removed from the settling chamber without having it mix with undigested sewage solids.

.Figure'3 is a horizontal sectional view throughv the settling chamber; I

Figure 4 is a fragmentary sectional view showing the gate operating means,

Referring to {the i drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotesan outside wall-'structureand numeral 6 an -inside wall ;st ructure.- The wall gate I5 is resting .againstthe same the uppermost surface of the gate-will be 'fiush. with the uppermost surface of the corresponding sloping wall portion; I

Bearing elements 11 are located on the partition head :III and are secured in place'by' bolts. l8 anchored in'the head 10 and equipped with nut I I9 adapted to befitagainstthe bearings H. An elongatedshaft 20 extendsthrough the bearings I1 andhas theigate liprojecting laterally therefrom. I v I One end wall Zlhas a tube 22 extending therethrough and, terminating ,inarecess 23 at the inner' side of the wall 2 I, at-which point the tube 22' is equipped with atcap 24, v 'Astub shaft .25v "having its inner end reduced as at 26for interlapped relation with-a correspondingly shaped end 'of'the shaft'lll is provided withla collar 21 located within'the recess' 23 and this collar 21 e V has set screws extending through the same to bite into the stub shaft '25. s v

An; elongated sleeve-29 extends through the tube 22 to abut thecapz l and the outer end of this. sleeve 29 and-the adjacent end of the tube 22 are provided with outwardly disposed flanges ;30 and 3| respectively; interconnected by bolts 32. 7

The stub shaft] 25 extends outwardly-beyond the outer end of the sleeve 29, and has a polygorial-shaped recess for 'receiving a-jpolygonalshaped stub memberv 33,onyafcrank handle 34, I

the rotation of whichgwill swing the" gate l5 either ,to one, wall I l or the other so that the sewage canibe easily removed from one chamber, suchas the chamber l3,.,after it has digested, without in any way mixing with the sewage such as raw solids located in the chamber 14.

4 Further, sewagejsolidscan be allowedto settle structure 5 has inwardly sloping bottom portions.

I merging with a flat bottom 8 from which rises a partition 9 terminating at its upper edge in a longitudinally extending enlargement or head H). The wall structure 6 isprovided with inwardly extending andgsloping bottom portions l l which terminate at their lower' edges in. close spaced,

relation to leave a slot l2;thr ou'gh which'sewage,

can pass to reach either thesludge chamber l3 or the sludge chamber I4, depending upon the position of a gate l5 mounted on the head ID of the partition 9. The lower portion of the sloping bottoms 'l I of the wall structure 6 are reduced as T at It so that when the free edge portion ofthe intothejchamber. 13 without injanyway mixing I with the half or wholly digested sewage solidsin ;the'chamberl4.

Whileythe foregoing specifications sets forth the invention-in specific termsit is-to be under; stood that numerous changes in the shape, size and materials may be resorted to withoutdepart- I v ing from the spirit and scope of the invention as claimed hereinafter. j i 1 I Having described the invention; what is claimed as new is: j 1 z r I A sewer disposal structure comprising a receiv ing chamber, a settling chamber, saidreoeiving chamberhaving an elongated narrow opening in the bottom thereof; a riser on the bottom of the settling chamberjdividing the settling chamber into a pair of, separated sewage receiving compartments, :upstanding'threaded members I anchored in the riser, a bearing plate having openings therein disposed on the riser and having the threaded members extending through said openings, nuts on the upper ends of the threaded members for holding the plate against the riser,

bearings on the plate, a shaft journaled through the bearings and provided with a laterally disposed gate projecting upwardly to terminate within the narrow opening and adapted to engage the lower portions of the receiving chamber at the narrow opening at either one side or the other depending upon the position to which the 5 shaft is moved.
